Time-Aware Evidence Ranking for Fact-Checking [article]

Liesbeth Allein, Isabelle Augenstein, Marie-Francine Moens
2021 arXiv   pre-print
Evidence ranking in three fact-checking models is ultimately optimized using a learning-to-rank loss function.  ...  Truth can vary over time. Fact-checking decisions on claim veracity should therefore take into account temporal information of both the claim and supporting or refuting evidence.  ...  Neither the European Commission nor any person acting on behalf of the Commission is responsible for the use which might be made of this publication.  ...

Our study show that 10 health awareness events are effective with evidence of a significant increase in search frequencies in the event months, and 28 events are ineffective, with the rest being classified  ...  It would be informative and instructive for the organization to know the impact of these events, although such information could be difficult to measure.  ...  In fact, we checked the relative frequencies across effective, unclear, and ineffective events, and found that there is no relationship.  ...
